Hi, several times, when towing, my car has thrown up the ASC System Requires Service warning and I have been able to pull over, wait a bit, restart and travel on. My Mitsi service workshop cannot identify why this happens. Two days ago I got that message plus the engine warning light and the car dropped into limp home mode; tried the usual but the engine light stayed on. Still drives okay but I'm only going short trips until I get expert help ( the book says should be okay). Has anyone had similar problems that got fixed and how, please?
